51st Oza Match Game 1

[Black "Habu Yoshiharu, Oza"]
[White "Watanabe Akira, Challenger"]
[Event "51st Oza-sen, Game 1"]
[Date "September 2nd 2003"]
1.P7g-7f     00:00:00  00:00:00

Even though Habu is only 32 at the start of this game, he has been at 
the top of the shogi world for so long that he can almost be considered 
a veteran. In contrast, his challenger Watanabe is only 19 years old and 
appears in his first title match ever. Many reporters saw this match as 
a fight between the Habu generation and the front runner of a new generation 
of teenage prodigies, many of which are still playing in the 3-dan league. 
How would Watanabe respond to the pressure of being the representative 
of a new generation in his first title match encounter with the magical 
Habu?

20.R8f-8e    00:36:00  00:19:00

Habu likes to meet his opponents head-on. He played Watanabe only once 
before and then avoided his opponent's specialty and played Furibisha 
instead. Even though he won this game fairly easily, a title match is 
a completely different ball game. Beating your opponent in the opening 
he likes best carries over to the rest of the match, so Habu allows 
Watanabe to play his favorite opening: the R8e Yokofudori.

Diagram 1

A new move by Watanabe. Even though he is a proclaimed hater of studying 
opening theory, he will have had this position on the board at home as 
it occurred in the game between Sato and Tanigawa in the final of the 
preliminary group 1 of the Ryu-O tournament this year. Tanigawa played 
32.S6b there, but Watanabe's 32.G6b is an improvement. The king now 
has an escape route through 6a and 7b, which can be an important 
difference in the endgame.

33.P*2c      02:18:00  02:09:00

The pawn on 7d is blocking the important side-ways working of the rook 
and that is why Habu decided to attack at this point. It is very hard 
to say if this is the right decision...

44.P*2h?!    02:49:00  03:58:00

Diagram 2

"Unexpected" was the euphemism Habu used concerning this move. In the 
press room, 44.P6d was considered much better. For example, 44.P6d 
Bx6d P7e Bx7e R2d G*6d B*3e and white has good fighting chances. Even 
44.P7e was generally regarded as superior to 44.P*2h. However, when 
asked after the game, Watanabe had no comments about this move. That 
was telling in itself, as he was by far the more lively talker during 
the post-mortem analysis. He might have simply overlooked the fact 
that black doesn¡Çt have to take this pawn.

45.S3i-4h!   03:01:00  03:58:00

Now black gets an important material advantage and a strong looking attack.

68.P5c-5d?   04:16:00  04:50:00

Watanabe has managed to keep the position very close, but this is a 
mistake. Better was 68.R5d! and after 69.+Bx5d +Bx5d G7g +P2h K6h N7c 
things are far from clear. The white king looks quite vulnerable, but 
the promoted bishop makes it very hard for black to find a good attack. 
On the other hand, white threatens to set up a good attack by himself 
with N*8e next.

69.G4i-3h!   04:21:00  04:50:00

Overlooked by Watanabe? 70.+Bx3h is mate in one after 71.Rx5d+, so this 
important promoted bishop will now disappear from its critical position.

82.K5c-6c?   04:42:00  04:59:00

Although Watanabe seemed to have resigned himself to losing this game 
after 69.G3h, Habu still thought that the position was difficult. Only 
here he felt that Watanabe made the final mistake. He was worried about 
82.Bx2g+. This looks very dangerous after 83.+Rx4c K6d P*6e Kx6e B4g 
K6d, but black has to be quick with his attack and can only mate with 
a pawn drop in this position. Allowing +Rx4c usually means game over, 
but this might have been an exception. One minute of byoyomi was not 
enough for Watanabe to see his final chance.

Final Diagram

And black wins after 96.K6c Gx7d Kx7d (K6b +Rx5c followed by G*4c leads 
to mate) +Rx5c which leaves white without defense. A game that seems to 
show Watanabe's of experience at this level. The question is if he will 
be able to learn quickly enough to get back in such a short match. The 
next game is already one that he must win.
